The JBO Thread Ring Gauge NoGo in Metric Fine is a precision tool engineered to verify external thread diameters on components with metric fine threads. Sized for right-hand M38 x 1.5 threads, it helps inspectors, machinists, and quality teams confirm parts meet exact standards with quick, reliable checks.

Built for demanding environments, the NoGo gauge emphasizes practical accuracy and durable performance, so you can rely on consistent results across busy production runs.

• No-Go Verification for Quick Pass/Fail: Quickly confirms whether an external thread exceeds tolerance, enabling fast QC decisions and reducing rework.
• Durable Hardened Steel Construction: Hardened steel design resists wear and maintains accuracy even after repeated use in challenging workshop conditions.
• Precisely Machined for Metric Fine M38 x 1.5: Specifically tuned to the M38 x 1.5 right-hand thread, delivering repeatable measurements and reliable compatibility with compliant parts.

The gauge streamlines inspection workflows by turning complex thread checks into simple go/no-go tests, helping ensure every component threads cleanly and assemblies fit correctly. Its rugged construction supports a long service life in metalworking environments, while the metric-specific sizing provides confidence that parts meet exact tolerances—reducing downtime, preventing mismatches, and supporting accurate quality records.
